Another MK8 Minimalistic replacement

Okay, so I think there is something almost exactly like this somewhere in thingiverse.
I just wanted a minimalistic replacement that doesn't use a spring. And could be adjusted with only an Allen wrench. That is why it has a nut trap.
This uses a 3mm x 20mm cap screws, a 4mm screw, a 3mm nut, and one 624 (5mm x 13mm x 4mm) bearing.
